目的：评价3．0T 磁共振扩散加权成像（DWI）表观扩散系数（ADC 值）在鉴别卵巢实性肿块良恶性的价值。方法：42例卵巢实性肿块（23例卵巢实性良性肿瘤，19例恶性卵巢肿瘤）前瞻性行 MRI 及 DWI-MRI 检查。所有病例均经组织病理学证实。将14例阔韧带平滑肌瘤作为对照组，所有病例的生物学特征及 ADC 值分别进行记录、测量，并进行组间比较。结果：良性实性卵巢肿瘤[（1．16±0．47）×10-3 mm2/s]同恶性实性肿瘤[（1．33±0．48）×10-3 mm2/s]间 ADC 值差异不具统计学意义（P ＝0．234），均低于韧带平滑肌瘤[（1．48±0．42）×10-3 mm2/s]。良性卵巢实性肿块和韧带平滑肌瘤间 ADC 值具有统计学显著差异（P ＝0．043）。结论：ADC 值无助于鉴别卵巢实性肿块的良恶性，但有助于将良性实性卵巢肿块和阔韧带平滑肌瘤相区分。

Objective:To investigate the value of MR diffusion weighted imaging (DWI)with a 3.0T (3T)unit,u-sing apparent diffusion coefficient (ADC)technique in differentiating ovarian solid masses.Methods 42 ovarian solid masses including 23 benign and 19 malignant masses were recruited.All cases had prospective MR DWI and proved by pathology afterwards.Taking 14 cases of broad ligament leiomyoma as control group.The biology characteristics and ADC values were recorded,measured and compared.Results:The mean ADC value of benign solid masses was [(1.16±0.47)×10 -3 mm2/s], with no statistic difference when compared with that of malignant solid masses [(1.33±0.48)×10 -3 mm2/s](P =0.234). The ADC value of benign and malignant ovarian solid masses were lower than that of broad ligament leiomyoma [(1.48± 0.42)×10 -3 mm2/s].There was significant statistic difference when comparing the ADC value of benign ovarian solid mass and broad ligament leiomyoma (P =0.043).Conclusion:ADC value was useless in differentiating benign and malignant ovar-ian solid mass;however,it was useful in discriminating benign ovarian solid mass from leiomyoma.
